Anatomy
| The body of a Plesiosaur was broad and relatively compact, with closely set, strong ribs and well developed gastralia protecting the belly. The limbs were also very large and modified into well developed paddles or flippers which were the main means of propulsion. Evidence has shown that the flippers on the Plesiosaur were probably used like wings on a bird instead of paddles on a rowboat. The Plesiosaur, in effect, flew through the water (Everhart, 1998). | |
